Method:
1. Blend passionfruit pulp in a food processor to break up seeds from juices.

2. Chop white chocolate finely and put in a bowl.

3. Over a low heat, bring cream and passionfruit pulp to a boil

4. Strain over white chocolate then mix until melted.

5. Refrigerate ganache overnight.

6. Using a melon baller and very wet hands, scoop out cold ganache and roll into balls. Do this quickly so the ganache has as little contact with your hands as possible. Keep dipping hands into water between each ball to prevent sticking. You may need to do in batches, returning ganache to fridge to firm up.

7. Put balls on grease-proof paper into the freezer for about an hour to firm up completely.

8. Melt the dark chocolate then allow it to cool for 5-10 minutes (depends how warm your kitchen is).

9. Roll the ganache balls in the dark chocolate then return to fridge to harden up. Make sure dark chocolate covers ganache completely or when it hardens and expands the ganache will squirt out (I learnt the hard way).

10. Remove from fridge just before eating.
